Serial No. 169,586.

billing machine, such as disclosed in French Patent No. 383,719 granted January 16, 1908. to Hubert Hopkins, and application for United States Letters Patent filed April 9, 1906, Serial No. 310,739.

One of the features of my present invention is to provide a, lock for the tabulating bar to hold it in its lowered and raised positions; another of the features of my invention is to provide a multiple control for the tabulatiug mechanism which, briefly stated, may be divided .into four parts; first, the positioning of the tabulating bar directly upon the operation of the tabulating keythis may be done before any operation of the adding mechanism of the machine; second, positionin the tabulating bar coincidentally with t e operation of the adding machine and near the'end of the final movement thereof, 1'. 6-, after the recording de-' footing an operation of the adding mechanism.

Other features'of my invention reside in the locking and releasing devices for the several parts whereby each is held in position until its proper function is performed Fig. 7 is an enlarged front elcvatlonal view of the upper end of the t'abulating bar and then restored, or ermitted to be restored,'.to normal position in readiness for another operation.

In the drawings, 1 indicates a platen of a laterally movable paper carriageand 2 are the keys of the typewriting mechanism for recording letters and words and figures upon the papler as in writing in the item and date on a bi pinion 4 on the upper end of a shaft 5, said shaft being designed to be coupled to a constantly rotating shaft 6 through the medium of a clutch or back-spacing or returning the carriage to its normal position by the use of mechanism such as shown in United States Letters Patent No. 1,096,074 granted to me May 12, 1914, (back spacing mechanism for paper carriages) and United States Letters atent No. 1,120,862 granted to me December 15, 1914, (carriage return mechanism). The motor drive for the calculating maor invoice, etc. 3 is a rack on .the carriage with which meshes a IOU chine, which motor also drives the carriage return and back-spacing mechanisms above referred to, is shown in the Hubert Hopkins Patent No. 1,025,398 granted May 7, 1912, and with respect to these various mecha-' nisms, parts of which are shown in the. accompanying drawing, it is unnecessary to give full and complete description except to state that 6 is the motor which through suitable gearing, drives the shaft'7, said shaft carrying a. crank arm 8 to which is attached a link 9, the upper end of said link being connected to a rock arm 10 on the rec shaft 11 which carries a locking member 12 having a pin 13. This pin coiiperates with a tappet 14 on the end of a rock arm 15 mounted on rock shaft 16, on which shaft is a forwardly extending rock arm 17 carrying an adjustable impinging member in the form of a screw 18 designed to lift the tabu lating bar under certain conditions, as will hereinafter appear, whereby the crank arm 8 which is caused to make one com lete revolution is undercontrol of a bar 19 av ing a laterall projecting pin designed to cooperate wi an inclined face on the u per edge of a bar 20. Thede'tails'bf this motor clutch mechanism are fully strewn and described in the Hubert HopkinsPat-i out No. 1,025,698, before referred to, andas they form no pgrt of. mygaresentinvention, they need not further ascribed here? It is necessary, however,'in connecting the crank arm 8 to the motor to efl'ect an operation of the adding machine, to move the bar 20 forwardly where it remams while'the mofor key is depressed and just before the crank arm reaches a full completion of its revolu-. tion, means, shownjn the Hubert Hopkins patent last mentioned, are provided for restoring themotor ,bar'20, orsuchother bars as may,when operated, raise the clutclrbar 1,9 and coincidentally'with 't restoration of the bar 20, move said bar r arwardly'and at the same time raise the motor key. connected thereto. Bar 20' is connected b a rod 21 to a bell crank 22 which bell cra may be op erated by the motor key 23 (see .Figs. 1, '2 and 3). Thus when the key 23 is de resse bar 20 is pulled forwardly, clutch ar 19 is raised, and crank shaft 8 is caused to make a full revolution and 'ust prior to the completion of this full revo ution, bar 20is caused to move rearward! to permit the clutch bar 19 to descend, ereby disengagin the motor clutch.

in making out bills and invoices where the dates and items are written in on the typewriting mechanism, a tabulating key marked 25 may be depressed to release the paper carriage permitting its leftward movement until arrested in a position where the amount of the item set up on the digit keys of the typewriter is to be registered in the totalizer and recorded in the column of figures at the right of the items so that a correct addition of all the items may be obtained and recorded at the bottom thereof. The use of the tabulating mechanism is of course old in typewriters and tabulating devices have been employed in combined adding and typewriting machines in the manner just referred to and now about to be described. The tabulating ,key 25 is connected to a bell'crank lever 26 to which is attached a rod 27 having its rear end connected to a rocking lever 28 mounted in a bracket securedto the base of the machine (see Fig. 3). This bell crank lever 28 has an upward extension at its rear end to which is connected a bar 29, said her having a slot in its upper end through which slot passes a rod 30. Normally this 'rod 30 lies in the lower end of the slot of bar 29 and consequently while the inner end of rod 30 may be raised, movin idly in said slot, the lifting of bar 29 wil cause the inner end of bar 30 to be-raised.. The inner end of bar 30 suptplort in abracket 32 secured to the frame of '0 machine '(seeFig. 4).

The operation of the tabulating key. 25

through; the instrumentalitie's just above described simpl results in lifting the tabulating bar 31- an in this respect, by lifting said flhe'iup rf; end of the tabulating batis guided y a-Ifil0tand pin cdnnection in a casing a'i'rangd on the'top frame plate 36; 'of the 'ty writing machine, -said 'bar bein provideK with alaterabpro'ection' 37 wlgic normall is ulled againstt a face of the lug 38, fixe in tli bar,3 1is raised by the 'tabulatin key,'as shown by dotted lines in Fig. 6, t a lateral projection 37 when it reaches a point above the lug 38 will permit the up e'r end of the tabulating bar. to be move rightwardl under the impellin action of spring 34' sai lateral projection, by thus assm above the lug 38,. locking the tab atin ar in its raised position. In being mi and moving rightward] as above described, the tabulating bar wi I operate a lever 39 whose lower end engages a notch in a and bar 40. A spring 41 tends to hold't elower end of lever 39 in engagement with the guard bar at all times. A s ring 42 tends to lift the guard bar at all times, said guard bar havmg a head portion 40 lying across the lug e housing35. When the finds'supportin the lower end oftabulating -bar;31, whilethe'ou'ter end of bar'30 find;

38 and an inclined edge 40, as shown in Figs. 6, 8, 10 and 11. Thus whenever the tabulating bar 31 is raised the strength of spring 34 will rock the restraining lever 39 when the tabulating bar is raised, such restraining lever, upon being rocked, releasing the guard bar and permitting it to rise to the position shown in Fig. 11. indicates a restoring lever for the guard bar pivotally mounted on the housing 35 and having a slot 45 for receiving a in 40 carried by a cross arm on the guard member 40. The upper end of guard lever 45 is provided with a lateral projection whose side edges are beveled or inclined as shown in Fig. 9, this lateral projection normally lying above and slightlfyto one side of the beveled upper en' '0 the tabulating bar 31. By the slot and pin connection, just above described, the guard barand its restoring lever move upwardly in unison as shown in Fig. 11, the guard bar serving to revent rebound of the carriage by risin be ind the lug 46 after said lug passes t 'ercover. The lug, after passing over the upper end of the tabulatm lever, engagesthe restoring lever 45 and fa ly depresses the ard bar 40 to its lowest position, where it is locked by the lever or bar 39. In moving leftwardly, the tooth 46 of the adjustable block 46 will thus first strike the. inclined face 40" of the guard member 40, depressingthe same and the guard lever 4 5 (but not to their-fullest ,extent), until tooth 46 is arrested by the upwardly projecting end of the tabulating bar, at which time the guard member is again in its elevated position to prevent rebound of the carriage. Before reaching its final point of arrest, the tooth 46* will move the upper end of the tabulating bar leftwardly until the projection 37 passes beyond the lug 38 at which time the,spring 34 will draw the tabulating bar downwardly. The movement of the upper end of tabulating bar leftwardly "will enable the lever 39 to reengage the guard 'bar' 40'when the restoring lever 45 moves it to its lowest position, whereby lever 39 will lock said parts in their full depressed positioni The tabulating bar 31 has a shoulder 31 near its upper end which engages a rocking plate 50 so as to move the escapement pinion rearwardly out of mesh with the rack on the paper carriage when the tabulating bar is lifted. When the tabulating bar is depressed, the spring 51 hearing against the upper end of shaft 5 reengages the escapement pinion with the rack which thereby becomes a lock for the paper carriage to prevent further leftward movement thereof.

Each of the blocks .46 is provided with a set screw 46" designed to engage a Hat upper face of shaft 47, the rearwardly extendin portion of block 46 being provided witli teeth or projections to engage notches in the track rail 52 of the paper carriage whereby after described, will cause the adding mcchanism to be operated to record num ers on the paper carried by the platen m such column or position on the paper as may have been determined by the operation of the tabulating key, if the same had been depressed. The release of the tabulating bar upon being moved leftwardly from its raised and locked position will enable it to be restored by the action of spring 34 independ ontly of any operation of the motor driven adding machine and consequently such restoration occurs coincidentally and immediately following the depression of the tabulating key.

The motor key 23, before described, rocks the arm 17, liy first raising and then lowermg said arm, such rocking movement occu r. ring ust before the final movement,,or

what might be termed the back stroke of the f power driven rock shaft 11. The bar 30,

before referred to, is provided with a collar 30 which collar normally lies in the path of movement. of the adjustable lifting screw 18 and consequently as the bar 30 is mounted in the tabulating bar 31, the upward movement of arm 17 will raise the tabulating bar; hence, by depressing the motor. key. 23 and independently of any previous operation of the tabulating key 25, the adding mechanism will be caused to make ancifcctivc operation in registering and recording an item or a. number after which, and just before the final completion of such adding machine movement, the tabulating bar 1 will be restored. This automatic operation of the tabulating mechanism following the registration of and recording of a number in and by the adding mechanism is of importance in connection with statistical -work, wherein the numbers so recorded are to be arranged in column order. It may be de -sirahle at times to operate the tabulating mechanism automatically and in connection with the operation of the motor key, before an effective movement of the adding mechanism, as in statistical work, but at other times it is desirable to operate the adding mechanism independently of any operation of the tabulating mechanism. In other words, while the tabulating mechanism is in readiness for operation upon the deprcs sion of hue motor key (motor key 23), the depression of another motor key (motor key 60) will disable the tabulator control and prevent the raising of the tabulating bar. The motor key 60 is arranged upon the forward end of the bell crank lever 61 having rearward extension to which is pivotally connected a link 02 said link having a slot and pin connection with the bell crank lever 22 of the motor key 23. A spring 63 tends to hold the motor key 60 in its normally raised position. However, when the motor key (30 is depressed it will rock the bell crank 22 and move the motor bar 20 forwardly which is equivalent to a depression of the motor key 23. \Vhcn the motor key 23 is depressed, through the slot and pin connection just above referred to, the motor key 60 will not be depressed. In other words, key .23 operates its connections without operating any of the connections of the key 60; but depression of the key 60 not only operates its connections but also the connections of key 23. Rod 64 is one of the connections operated by the key '60, said rod bein connected to thelower end of a rockingl cvcr 65. the upper end of which rocking lever being located in front of a. T-shaped lever 66 pivoted on a lug.extending from the frame bar 33. The forwardly extending member of this T-shaped lever is provided with an opening which engages-a pin 30" on rod 30 and consequently when motor key 60 is depressed, rod 30 will be moved rightwardly, carrying with it the collar 30 so as to locate said collar to one side, the right, of the path of movement of the lifting screw 18. Hence, while the collar 30 may be located over the lifting screw 18 in a position to lift the tabulating bar 31 whenever the motor key 23 is depressed, the depression of the motork'ey 60 will move the collar 30' rightwardly out of the path of the lifting screw 18 and thus disable the tabulating bar lifting mechanism. By this means, the adding mechanism may be made to operate through the motor driven conncctions controlled by the motor key -60, while the tabulating bar remains inactive.

Means are provided for locking the collar 30 in its displaced position during the time that the motor kev 60 is depressed and until just before the adding machine mechanism completes its final movement. It has been described that when the motor kc 23 is depressed, the lifting of the tabulatmg bar incident to such depression will occur just before the completion of the final stroke of the main 0 crating shaft of the adding machine. It ollows, therefore, that to hold the collar 30 displaced during the vibration of the lifting screw 18, or at least the upward stroke thereof, that such displacing means should not be released until the lifting screw is either nearing the upward limit of its shaft 16 causing movement or has started to descend below the collar 30. The locking mechanism for the collar 30' and the rod 30 on which it is carried, comprises a. bar 70 having one end connected to the T-shaped lever 66 and the other end guided by a slot and in connection with the frame bar 33. This bar 70 is provided with a shoulder 70 which cooperates with a shoulder 71' on a locking pawl 71. This locking awl is normally pulled down by a spring 2 so that when the bar 70 is moved rightwardly, as shown in Fig. 5, the end of pawl 71 will drop behind the shoulder 70', as shown in said figure, its downward movement being arrested by 9. lug or bracket 33extending from the frame bar 30. 74 indicates a complementary locking pawl pivotally mounted on the extension 33' and whose end is normally held raised by a spring 75. A lateral extension 74 projecting under the lug 33' limits the upward movement of the forward end of this lockingmembcr 74. (See Fig.3. It hasbeen be ore described that the sha 11, which is mechanism, is rocked first -forwardly no then backwardly at every complete revolu: tionv of the motor driven crank arm 8. On shaft 16, which is part-of the addingma china mechanism, is a rock arm 76 onwhich is mounted a bar 77 provided with a pin 78 the 'main operating shaft of the adding lying under the rear .end of the locking member 74. When the motor key 60 is depressed,"

'it will, through theconnections above described, move the bar 70.'ri'ghtwardly until the end of pawl'71 lies behind the shoulder 70}, thus locking said bar in its htward position and'oonsequently holding a collar 30 displaced and out of the path of the lifting screw 18. Upon-the depression; of the motor he 60, the motor will rock the the bar 77 to descend and consequently m 78 will be moved downwardly away ing member 74, thus permitting the forward end of said locking member to rise under the impelling action of its spring so as to locate the forward end of the member 74 behind the shoulder 70". The power of spring 75 is sutiicient to lift the end of the loc ing pawl 71 above the shoulder 70? so that this in the rear end of the lockocking pawl is raised out of looking on gement with the bar 70 and said bar 0 is restrained from ri htward movement by the front end of mem r 74. Of course, there is suflicient clearance of the parts to permit this operation, that is, the original displaced position of the bar 70 when it is temporal-gay held by the end of pawl 71 provides an cient clearance for the movement of the forward end of the locking member 74 behind the shoulder 70; and the lifting movement of the foward end of the locking member 74.

is sufficiently great to carry the end of the locking pawl 71 above the shoulder of the bar 70 permitting a slight leftward movement of bar 70 to take up the clearance previously provided and which slight leftward movement of bar 7 0 will locate the shoulder 70 under the end of the locking pawl 71 (Fig. 3*). When the bar 77 rises, and just before it completes its final movement, the pin 78 will engage the rear end of the lockmg members 74 lifting it and depressing the forward end out of engagement with the shoulder 70. This depression of the forward end of the member 74 continues until about the time all the parts are in their home position when the forward end of said rocking member 74 will release bar 70 and permit its leftward movement to normal position.

The parts above described presuppose desired operations of the machine wherein, (1) the tabulatin mechanism can be independentl actuate d before any operation of the adding machine; (2) the automatic operation of the tabulating mechanism as an'incident to the operation of the adding mechanism upon the depression of a iven motor key; and (3) the displacement o the control devices of the tabulating mechanism whereby it is inactive during the operation of the adding mechanism incident to the depression of another motor key,

n It is sometimes desirable to permanently:

disable the tabulating mechanism from any motor key control and this is accomplished by providing the rod with a. button 30 at its outer end by which said rod ma be manipulated by the operator. By fpu ing the rod outwardly, or to the right, an annulus 30* is brought in alinement with the locking bell crank 80 pivotally mounted upon the bracket 32 and whose lower end is designed to enter the annulus 30 and prevent inward movement of the rod 30. A

s ring 81.is connected to the lower end of t e bell crank to hold it in its locked position. By thus permanently holding the rod 30 in its rightward position, the collar 30 is displaced. with respect to the lifting screw 18 and consequently the operation of the motor driven parts cannot effect tabulation. When it is desired to restore rod 30 to an operative osition, the bell crank 80 is operated to re ease said'rod which will move inwardly' under theimpelling action of the spring connected to the T-shaped lever 66 to an operative position.

In the Hubert Hopkins French patent, before referred to, and United States application Serial No. 310,739, there is illustrated a. multiplying mechanism, the operation of the multiplying keys of which lifts the bar 19 independently of any depression of the motor key. In other words, the operation of any one of the multiplier keys indicated at 9() Fig. 2, is equivalent, so far as raisin the bar 19 is concerned, to depressinfi one o the motor keys 23 or 60, with this di erence,

however, that in said French patent means are provided for causing the crank arm 8 to make two complete revolutions instead of one, when the multiplier keys marked 2 to 9 are depressed. \Vhen the multiplier keys 1 or 0 are depressed, said crank arm will make only one revolution. lIVe are not 'concerned in this application with the multiplyin mechanism nor the means controlled by t 1e multiplier keys for causing the crank arm to make one or two revolutions as the case may be, but we are concerned with the fact that when the addmgmachine is operatin in the performance of multiplication, if t e collar 30' is located over the liftin screw 18, the tabulating bar will be raise at each rocking movement of the shaft 16, unless of course the operator takes the precaution to pull the rod 30 outwardly into what has been designated aS the permanently locked disabling position of the tabulating mechanism before starting the multiplying operation. To take care of this possible oversight on the part of the operator, means are provided to disable the tabulating mechanism whenever multiplication is being performed. This means consists of a bar 91 which bar is identified with the multiplying devices of the machine and vibrates at every revolution of the crankshaft 8 in the performance of multiplication. Bar 91 is connected to a bell crank lever 92 which in turn operates upon another bell crank lever 93 which latter has one of its arms extending down behind one member of the T-shaped lever 66. By this construction, whenever the bar-'91 is raised, it will operate the T- shaped lever 66 the same as if the motor key 60 was depressed, thereby displacing rod 30 and its carried collar 30, the locking devices coiiperatin with the rod 'IO- and being re leased by t e pin 78 in the manner heretofore described.
